Hello guys, this is my first post here! I just got a MIG Switch card out of curiosity and I was tinkering with it. For those who don't know, it's used by placing XCI dumps as well as other game specific bin files in the sd card of the MIG Switch, and are obtained from the original cartridge by using an app like nxdumptool. Two of these bin files are mandatory to get the game to boot: Initial Data.bin and Certificate.bin. They stay the same for every cartridge of a specific game. Now, if you want to use an XCI dump from a shady website it's impossible to get it to work without those files. By using the Certificate.bin from another game it has no problem, but this does not count for the Initial Data.bin. So I looked for a way to obtain this Initial Data from an XCI file and read a bit of the XCI file documentation from switchbrew dot org. Here's what I understood so far: The Switch checks if the cartridge is valid by doing a challenge–response authentication on the Initial Data. The Package ID is contained both on the XCI and the Initial Data, on positions 0x110 and 0x0 respectively. The Initial Data hash is on the XCI at position 0x160. It is calculated by doing a SHA-256 hash on the full Initial Data content. So I was wondering, is there a way to to construct a functional Initial Data file starting from an XCI dump? I also tried a reverse approach by editing the Package ID in the Initial Data from another game, generating the Initial Data hash and putting it in the XCI file but is not enough to get the Switch believe it's a real game. Sorry if this may seem stupid but let me know what you think.

Tutorial Updated

How to install the exFAT driver without updating!

This guide is outdated, use this easier guide instead: guide, original thread: ChoiDujourNX

*************

Warning: Use at your own risk, using a wrong version of a game dump could prevent the console from booting.

Warning: Because we install the driver without ever requesting this from Nintendo, this could be detected if you go online and result in a ban.

Intro:

How to install the exFAT driver without updating you console.
I used the game dump "Penny.Punching.Princess.NSW-BigBlueBox" on my 3.0.2 Switch.
I'm assuming you know how FG works and how to send payloads to the console before proceeding.

There are two methods of installing this:
1, Stock: Installing it to the system like a cartridge would. This works on stock firmware but exFAT support would be lost after a system update.
2, CFW: When booting Horizon via hekate, a .kip1 file will be injected. The console's eMMC remains unaltered and will not have the driver loaded when booting normally and not via hekate.

Method 1, Stock:

Necessities:

- A console with firmware version 2.0 or higher (does not work on 1.0.0)
- A Game dump with an update on it that is the same version as the console (tested: trimmed xci works)
- Switch encryption keys (these can't be shared, Google 'nswroms' to find them)
- patch.zip: link
- TegraRcmGUI / TegraRcmSmash (TegraRcmGUI)
- memloader (https://switchtools.sshnuke.net/)
- HacDiskMount (https://switchtools.sshnuke.net/)

Steps:

step 1: Copy the contents of the sample directory of memloaderv1.zip to the root of your SD card.
step 2: Enter RCM using your prefered method: how-to-test-fusee-gelee.
step 3: Inject the memloader.bin payload that is located inside of memloaderv1.zip.
step 4: Select 'ums_emmc.ini' by navigating with the volume buttons and confirming with the power button.
step 5: open HacDiskMount as administrator and select 'Linux UMS disk 0':

step 6: Double click BCPKG2-1-Normal-Main and a window will pop-up:

step 7: Use the 'Start' button in the 'Dump to file' section to extract the partition.
step 8: (!) Create a backup of BCPKG2-1-Normal-Main.bin and store it somewhere safe.
step 9: Create a new directory and extract the contents of patch.zip into it.
step 10: Copy the game dump and BCPKG2-1-Normal-Main.bin to the same directory.
step 11: Create a file named keys.txt in the same directory.
step 12: Copy all of the Switch encryption keys to this file.

The keys.txt file should contain at least the following keys, replace the ... with the keys you found online.

master_key_00 = ...
master_key_01 = ...
master_key_02 = ...
master_key_03 = ...
master_key_04 = ...
aes_kek_generation_source = ...
aes_key_generation_source = ...
key_area_key_application_source = ...
header_kek_source = ...
header_key_source = ...

step 13: Inside of the directory we created, drag the game dump .xci onto the patch.bat file.
step 14: If the process executed successfully you should see something like this:

(The number of bytes can vary)
(Don't worry about the 'Failed to match key' warnings)
step 15: Go back to HacDiskMount and click on 'Browse' in the 'Restore from file' section and select BCPKG2-1-Normal-Main.bin that we just patched.
step 16: Close the pop-up window and doucle click on BCPKG2-2-Normal-Sub.
step 17: Repeat step 15 and restore the same BCPKG2-1-Normal-Main.bin file (optional, but advised).
step 18: Hold the power button on your Switch for 12 seconds to turn it off and then boot it again to see the results!

Method 2, CFW:

Necessities:

- Everything from method 1, except: memloader and HacDiskMount
- sdfiles.zip (https://github.com/tumGER/SDFilesSwitch/releases)
- hekate (https://github.com/CTCaer/hekate/releases)

Steps:

step 1: Create a new directory and extract the contents of patch.zip into it.
step 2: Copy the game dump to the same directory.
step 3: Create a file named keys.txt in the same directory.
step 4: Copy all of the Switch encryption keys to this file.

step 6: Inside of the directory we created, drag the game dump .xci onto the patch-cfw.bat file.
step 7: If the process executed successfully you should see something like this:

step 8: Copy the file FS.kip1 that was just created in the 'out' directory, to the root of your SD card.
step 8: Copy the contents of sdfiles.zip to the root of your SD card.
step 9: On your SD card, open hekate_ipl.ini inside of a text editor.
step 10: Add the following line below each boot entry that you want to inject:

Code:

kip1=FS.kip1

A boot entry is a line that starts with [ and ends with ], for example:

Code:

[CFW]
kip1=modules/newfirm/loader.kip
kip1=modules/newfirm/sm.kip
kip1=FS.kip1

step 11: Put the SD card back into your Switch.
step 12: Enter RCM using your prefered method: how-to-test-fusee-gelee.
step 13: Inject the hekate.bin payload

After booting hekate and selecting either 'stock' or 'CFW' from the 'Launch firmware' section, the exFAT driver will be injected!

Okay i will try it after work. What do i have to do after this?
Is it possible to use a NAND backup from someone else?

no, okay, do you have your biskeys dumped?

I saved the biskeys. what should i do now?

Now this is the hard part, you basically need to reflash the firmware using the old choidujour method. (This guide)

Provided you have the get the same firmware version you had (5.1 = 5.1 6.1 = 6.1 etc) you should be able to skip steps
8.1 8.2 and 8.3. BE WARNED IF YOU MESS UP THIS YOU DON'T GET A SECOND CHANCE

Okay, thanks. I will try this one, but before I do it, i will do a NAND backup this time ^^. Thank you for you help, i will tell you if it works or not.

I need a game to do this guide, right? I have 6.2.0 on my Switch. Is there any game i can use for it?

Do a nand backup AFTER you get it working. Basically if you follow that guide and you get a pop up DO NOT CLICK FORMAT WHATEVER YOU DO

If you click format there is no coming back
